Jay fills a wagon with sand (about 20 kg) and pulls it with a rope 40 m along the beach. He holds the rope 25â above the horizon

never [62]

Answer:

W = 725 J

Explanation:

given,

mass of wagon = 20 kg

distance of pull = 40 m

angle made with the horizontal = 25°

tension force on the wagon = 20 N

Work done = ?

Horizontal component of the force will help in movement of the wagon.

Horizontal component of force=

F_x = F cos θ

Work done is equal to force into displacement

W = F.s

W = F cos θ.s

W = 20 cos 25° x 40

W = 725 J

hence, work done on pulling the wagon is equal to W = 725 J

A 55 newton force applied on an object moves the object 10 meters in the same direction as the force. What is the value of work

Elanso [62]

$F=55 \ N \\ d=10 \ m \\ \boxed{W-?} \\ \bold{Solving:} \\ \boxed{W=F \cdot d} \\ W=55\ N \cdot 10 \ m \\ \Rightarrow \boxed{W=550 \ J}$

The equation for distance is d = st. If a car has a speed of 85 m/s and travels

Ludmilka [50]

Answer:

D) 10 200 m

Explanation:

Speed is known as the rate of change of distance.

$speed=\frac{distance}{time}$

distance = speed * time

= 85 ms⁻¹ * 120 s

= 10200 m
